Working Principles

MC74VHC4051MEL operates based on the principle of analog multiplexing. It uses the select inputs (S0, S1, S2) to determine which input channel is connected to the common output (Z). The enable input (E) controls the overall operation of the IC.

When a specific combination of select inputs is applied, the corresponding input channel is connected to the common output. The break-before-make switching action ensures that there are no short-circuits during the switching process.
